This study found no immediate cognitive effects from 902 MHz cell phone radiation in children during brief test sessions.

Plain English Summary

Summary written for general audiences

Researchers tested whether 902 MHz cell phone radiation affects children's thinking abilities by having 32 kids aged 10-14 take cognitive tests while exposed to both active and inactive phones. They found no differences in reaction time or accuracy between the two conditions. This challenges earlier studies suggesting cell phone radiation might actually improve cognitive performance.

Study Details

The present study investigated the potential effects of a standard 902 MHz global system for mobile communication (GSM) mobile phone on 10-14 years old children's cognitive function.

A total of 32 children (16 boys, 16 girls) participated with their own and parental consent. The sub...

The statistical analyses showed no significant differences between the mobile phone off and on condi...

It was concluded that a standard mobile phone has no effect on children's cognitive function as measured by response speed and accuracy. The present results challenge some earlier findings suggesting that the electromagnetic field (EMF) created by an active mobile phone would facilitate cognitive functioning.
